Ethernet continues to evolve as the network of choice for automation systems due to its high speed, familiarity among users, and ability to easily connect to the Internet. But the environment can be demanding. The equipment must be robust, reliable, and easy to install, maintain and use. It must carry proper regulatory approvals and, in some instances, withstand harsh outdoor temperatures. Office-grade equipment, with its frequent model changes and inconvenient mounting, does not stand up to these demanding needs.
Designed for unattended operation in environments not conducive to office-grade equipment, the Skorpion Series overcomes the challenges that Ethernet presents to the automation professional by providing convenient mounting in control panels, low-voltage power wiring, improved EMC compliance, and reliability. All Skorpion product enclosures are metal and intended for direct panel, rack or DIN-rail mounting. Metal DIN-rail clips prevent damage during installation. Most products can share with other automation equipment a common 24 VAC/VDC power source, eliminating the need for a dedicated mains-powered transformer. Most models have provisions for redundant power sources to accommodate back-up strategies in critical applications.
Plug-and-play unmanaged switches can be put into service without adjustments and provide a simple, cost-effective method for expanding Ethernet networks. Some models include features such as auto-MDIX and auto-negotiation.
The ultimate in performance and flexibility can be found in a SNMP compliant managed switch. By configuring the switch through either a web page or console screen, features such as virtual LANs, Quality of Service, cable redundancy and port mirroring can be invoked.
The diagnostic switch retains all the virtues of a switch with one exception—no address learning. All messages—directed, multicast, broadcast—are flooded to all ports on the switch allowing a protocol analyzer tool such as Wireshark the ability to observe all traffic on the network.
